ROHRE / AXIAL PISTON PUMPS
Pumps and OEM assemblies for semiconductor cleaning, reverse osmosis and high-pressure water mist.
Inside Rohre’s pump workshop — production, assembly and inspection.
01 / SEMICONDUCTOR
02 / WATER TREATMENT
03 / SYSTEM OEMs
01 / SEMICONDUCTOR & ULTRAPURE WATER
Rohre high-pressure pump in the equipment assembly area.
HPT SERIES PUMPS
For wafer cleaning and polishing-pad rinsing equipment. We review flow at operating pressure, inlet supply, water quality, wetted materials and the mechanical interfaces together.
SEMICONDUCTOR PROJECT / HPT 12.5
Specified normal flow
Specified normal pressure
Continuous VFD operation · 7.5 kW INNOMOTICS motor · Siemens SINAMICS V20
EXISTING EQUIPMENT
Send the Danfoss model, duty point, motor nameplate and installation drawing. We check performance, shaft and mounting fit, ports and any adapters needed.
NEW EQUIPMENT / OEM
Define the pump, motor and drive as one package. Share your layout, power supply, control interface and operating cycle so we can review the assembly scope.
02–03 / RO & WATER MIST
HPS SERIES / RO & SWRO
For desalination skids, marine watermakers and industrial RO. Compare flow at pressure and speed, feed-water conditions, corrosion resistance and the energy-recovery arrangement.
HPH SERIES / WATER MIST
For high-pressure water mist and humidification equipment. Define the simultaneous flow demand, working pressure, start sequence, motor supply and pump-package acceptance requirements.
ENGINEERING YOU CAN INSPECT
See the workshop processes and test records behind your pump. Agree the inspection points and acceptance requirements with our team before production.
01 / MATERIAL VERIFICATION
Material inspection of HPS components. Review the wetted-material and seal specification for the selected pump.
02 / PRECISION MACHINING
Slipper ball-head grinding in the workshop. Check the model drawing, shaft and mounting interfaces for your assembly.
03 / PERFORMANCE TESTING
Ultrapure-water pump test equipment. Agree flow, pressure, speed and the operating sequence to be recorded.
04 / DISPATCH PREPARATION
Pumps packed for shipment. Confirm identification, connection protection and the documents supplied with the order.
INSIDE THE TEST FILE
View the RO pump test sheet with operating readings, a curve and inspection sign-off, together with the test and packing photo record. For your order, agree the report and acceptance criteria for the exact model and package.
APPLICATION EXPERIENCE
SEMICONDUCTOR CLEANING
Frequent start-stop duty with three specified flow ranges.
HPT 2.0, HPT 4.0 and HPT 10 were selected for polishing-pad cleaning. The case also details an HPT 12.5 motor-and-drive package, materials and adapter connections.
ISLAND WATER SUPPLY
Two containerized SWRO trains, commissioned in May 2024.
The documented HPS11 application operates at approximately 60 bar and 10 m³/h per pump, with energy recovery included in the system design.
MARINE EQUIPMENT OEMs
Qualification of HPS 0.6, 0.8 and 1.0 pumps for marine systems.
Follow the evaluation process from sample pumps and on-system trials to factory review, batch testing and repeat supply. Includes model-specific duty data.
Rohre (Shanghai) Pumps Co., Ltd is a member of THINKTANK GROUP LIMITED, specializing in axial piston high-pressure pumps.
The pump line developed through a five-year OEM collaboration for water-mist systems. That manufacturing experience now supports ultrapure-water, RO and seawater applications.

Your equipment requirements determine the items included in the proposal.
SELECTION & SERVICE
01
Start with your application, flow, pressure, inlet conditions and power supply. Compare the selected model at your operating point.
02
Find HPS and HPH catalogues, performance curves, installation information and engineering resources for your equipment.
03
Identify the installed pump by model and serial number. Share the running conditions when you need parts or technical assistance.
TECHNICAL READING
Planning a Danfoss pure-water pump replacement? See how Rohre checks duty, inlet conditions, wetted materials and installation interfaces, with HPT dimensions and a semiconductor package example.
Explore Rohre HPT applications in semiconductor equipment, including a delivered 7 MPa duty and wafer-cleaning machines. Compare pump parameters and supply configurations against your requirements.
Danfoss APP pumps are widely used in seawater reverse osmosis systems. However, SWRO system integrators may need a more cost-effective high-pressure pump to improve
TALK TO ROHRE
Share your operating conditions and the equipment you are building or servicing. We can help review the pump, assembly scope and supporting documents.
Duty — flow, pressure and operating cycle
Water — quality, temperature and inlet supply
Integration — power, controls and connections
Replacing a pump? Include its nameplate and drawing. Developing a new module? Send your specification or layout, including any items still to be agreed.
Use the attachment field for a drawing, specification or nameplate photograph.
